2-Ketoglutaric acid (potassium)

2-Ketoglutaric acid (Alpha-Ketoglutaric acid) (potassium) is an intermediate in the production of ATP or GTP in the Krebs cycle. 2-Ketoglutaric acid potassium is a reversible and orally active inhibitor of tyrosinase with an IC50 value of 15 mM. 2-Ketoglutaric acid potassium also acts as the major carbon skeleton for nitrogen-assimilatory reactions. 2-Ketoglutaric acid potassium significantly suppresses abnormal intestinal permeability, delocalization of tight junction proteins from the intestinal cells, expression of TNFα in vitro and in vivo. 2-Ketoglutaric acid potassium directly binds to TAK1, and inhibits the TRAF6-TAK1 interaction. 2-Ketoglutaric acid potassium also alleviates inflammatory bowel disorder (IBD) symptoms and gut microbiota dysbiosis, evident by the improvements in the intestine length[3].
